Description

SCOPE OF THE INVENTION

[0001] The present disclosure relates to a head-worn optoelectronic imaging device. More specifically, the invention relates to a wearable system for real-time detection and visualization of electromagnetic radiation in the ultraviolet (UV) and near-infrared (NIR) range, which is normally imperceptible to the human eye. The device integrates a CCD-based imaging module, photocathode-enhanced optics, spectral filter units, and two virtual reality (VR) displays, making it suitable for scientific, industrial, and diagnostic applications. BACKGROUND OF THE INVENTION

[0002] Human vision is limited to the visible spectrum of electromagnetic radiation, approximately from 380 nm to 750 nm. However, numerous important physical and chemical phenomena—such as ultraviolet fluorescence, thermal emissions, and chemical reactions—occur in non-visible spectral regions such as the ultraviolet (UV) and near-infrared (NIR). Conventional systems using CCD sensors to visualize these spectra are largely limited to laboratory settings and are not portable.

[0003] Current portable imaging devices are either limited to visible light or offer rudimentary visualization of non-visible wavelengths without real-time capabilities or safety mechanisms. Furthermore, these systems often lack photon-sensitive materials or high-resolution display units, which are essential for practical field use.

[0004] Therefore, there is a need for a portable optoelectronic imaging device capable of visualizing non-visible light spectra in real time and with high sensitivity while ensuring user safety and comfort. SUMMARY OF THE INVENTION

[0005] The following is a simplified summary of the disclosed invention to facilitate understanding of its essential components and functions. This summary is intended as an introduction to the detailed description that follows.

[0006] Accordingly, the present invention provides an optoelectronic head-mounted display device configured to detect and display ultraviolet and near-infrared radiation.

[0007] According to one embodiment, the device comprises a CCD-based sensor module configured to detect electromagnetic radiation in the range of 100 nm to 1100 nm. The sensor is located behind a set of photocathode-coated lenses containing materials such as gallium (Ga), cesium (Cs), and bismuth (Bi), which enhance photoelectron emission upon exposure to high-energy photons.

[0008] The device also includes a spectral filter array configured to transmit UV and IR radiation while providing protection against harmful exposure. A dual OLED microdisplay system displays stereoscopic images in real time, enabling immersive virtual reality viewing. All active components are housed in a lightweight, insulated, and ergonomic head-mounted enclosure.

[0009] Optional features may include pseudo-color rendering, onboard storage, wireless connectivity, and augmented reality (AR) overlays.

[0010] The presented system allows the user to visualize invisible electromagnetic phenomena in real time, expanding the application possibilities in scientific diagnostics, industrial inspection and environmental monitoring. DETAILED DESCRIPTION

[0011] The various features and configurations of the optoelectronic headgear will now be described in detail. These embodiments are illustrative and not restrictive, and modifications may be made without departing from the spirit and scope of the invention.

[0012] According to one embodiment, the device comprises: 1. CCD sensor module: A highly sensitive CCD imaging unit is used to detect electromagnetic radiation in the range of approximately 100 nm (UV-C) to 1100 nm (NIR). The module is housed in a thermally insulated and electromagnetically shielded enclosure to minimize noise and interference. 2. Photocathode coated lenses: The lenses arranged in front of the CCD sensor are coated with photo-emitting elements such as gallium, cesium, or bismuth. These coatings amplify the emission of electrons when exposed to non-visible radiation, thereby amplifying the signal reaching the sensor and improving sensitivity to low-intensity sources. 3. Spectral filtering assembly: An optical filter mechanism is located between the lenses and the display components. The filter transmits UV and IR radiation while attenuating visible and harmful high-energy emissions. A lightweight UV blocker protects the user's eyes while ensuring effective spectral sensitivity. 4. Display system: The data processed by the sensor is transmitted to a dual OLED microdisplay configured for stereoscopic playback. The display unit is built into the headset to create a real-time VR environment. A protective screen layer minimizes exposure to internal emissions and increases component longevity. 5. Housing: All components are embedded in a head-mounted frame made of lightweight, insulated, and ergonomically designed materials. The housing is equipped with adjustable straps and passive or active thermal regulation systems to enable extended use.

[0013] Optional features: - Internal memory for image and video storage. - Bluetooth and Wi-Fi modules for wireless data transmission. - Pseudo-color rendering to distinguish spectral ranges. - AR overlays for contextual annotations and measurements. - Mode switching between pure UV, pure NIR and hybrid displays. - Miniaturization of components to reduce mass.

[0014] The device enables real-time visualization of electromagnetic radiation that is otherwise invisible to the human eye, making it an indispensable tool in specialized environments such as research laboratories, safety inspections, and diagnostic imaging.
